I’m moving a web-based product forward and need a senior-level developer who is truly fluent in Python. Your focus will be end-to-end web development: shaping the back-end logic, wiring it to a clean, responsive front-end, and ensuring the finished app deploys smoothly to production.

If you’re comfortable in frameworks such as Django, Flask, or FastAPI, you’ll feel right at home here—choose whichever tool best fits the task at hand. My expectations are straightforward: • Well-structured, idiomatic Python code pushed to Git regularly • Clear, concise documentation so future team members can extend your work • Unit and ...

Build a commercial Microsoft Excel add-in named MYAPP that provides a generic interface between Microsoft Excel and a Python backend. The purpose of the project is to create a reusable platform that allows predefined Excel worksheet functions to execute arbitrary Python code without requiring the user to install Python or perform any technical configuration. The Excel add-in must act as a lightweight client. It should collect function arguments from Excel, send them to a Python backend via HTTPS, receive the response, and display the result in the worksheet. The Python backend is responsible for all business logic. The backend should be able to execute any Python code required by the application, including calculations, database queries, integrations with external systems, document gen...

# Technical Specification: KYA (Know Your Agent) Cryptographic Middleware ## Objective We require a mid-to-senior backend developer to construct a secure "Know Your Agent" (KYA) verification middleware layer.

I’m assembling a real-time dashboard solution that must run smoothly on both web browsers and mobile devices. The front end will be built with modern HTML, CSS and vanilla JavaScript where appropriate, but React will drive the component logic and state management. On the back end I already have a FastAPI service in place; your task is to consume those endpoints, handle authentication with Firebase, and persist light local data through SQLite when the connection drops. The application needs to feel product-ready from day one: fast initial load, fluid charts that update live as new data streams in, and a UI that scales cleanly as we add new metrics. Efficiency and long-term maintainability matter more to me than quick hacks, so clear component structure and thoughtful API integratio...

Key requirements: - Python and FastAPI - FastMCP / MCP-based tool integration - Firestore - Angular front-end development - REST API design - Authentication, environment configuration, and secure API handling - ...

I need a Retrieval-Augmented Generation chatbot that can instantly answer employees’ questions about our internal HR policy documents. The bot must handle both text and voice input/output so users can type or speak their queries and receive the appropriate response in English. The first release will live inside our existing mobile app, so everything—from authentication to UI widgets—has to be optimized for iOS and Android deployment. A lightweight in-app webview is fine for the chat surface as long as it feels native and supports microphone access. Here’s what I expect: • End-to-end pipeline that chunks, embeds, and indexes my policy PDFs, Word files, and the occasional slide deck, then serves grounded answers using a modern LLM. • Clear separation b...

building a lightweight Android-only app whose single purpose is to generate random lottery numbers. The interface needs to stay simple and minimalistic—plain backgrounds, clean type, just one or two buttons—so users can open the app and get their numbers instantly. Here’s what matters: • Core feature: a lottery number generator only. No ticket-purchasing or results-checking at this stage. • Platform: native Android, targeting at least Android 8.0. Kotlin or Java is fine. • Look and feel: strictly minimal, using basic Material Components without flashy graphics. • Randomness: please rely on SecureRandom (or an equally strong method) rather than () for genuine unpredictability. • Configurability: all game rules (number range, draw size, bonus ball...
